Abstract

A promising domain-type meshless method is adopted to analyze the moving-boundary problems of sloshing phenomenon in a horizontally-excited numerical tank. When a tank partially filled with liquid is excited, the flow fields and the evolutionary profiles of free surface are known as the sloshing phenomenon. The local radial basis function collocation method is a newly-developed domain-type meshless method, so the time-consuming tasks of mesh generation and numerical quadrature can be avoided. The spatial derivatives at every node can be expressed as linear combination of nearby function values with different weighting, since the interpolation within every subdomain is achieved by function expansion of radial basis functions. Some numerical results and comparisons are provided to verify the merits of the proposed meshless scheme.
